WC-Co nyuaj alloys muaj qhov zoo ntawm microwave adaptability.Thaum lub sij hawm sintering txheej txheem, qhov poob hom uas ua hauj lwm nyob rau hauv lub qis kub cheeb tsam yog feem ntau polarization so loss thiab sib nqus poob, thaum nyob rau hauv lub kub cheeb tsam lub alloy absorbs microwave zog.Feem ntau nyob rau hauv daim ntawv ntawm dielectric poob thiab conductivity poob.
Covhlau alloynrog rau qhov sib ntxiv ntawm 0.4% VC thiab 0.2% Cr3C2 (feem feem ntau) raws li cov ntaub ntawv pabcuam muaj qhov ua tau zoo tshaj plaws;Kev siv lub tshuab nqus tsev microwave sintering ho txhim kho kev ua haujlwm ntawm cov hlau.Siv ntau kab noj hniav microwave sinteringWC-8 Co, nws yog sintered ntawm 1400 ° C yam tsis muaj cua sov preservation.Qhov ceev tuaj yeem ncav cuag 14.71g / cm3HRA mus txog90.3, thiab cov qauv zoo ib yam.
Microwave sintering thev naus laus zis tuaj yeem siv los npaj cov cermets ultra-nplua nrog cov nplej zoo, cov qauv zoo nkauj thiab kev ua haujlwm zoo heev.Raws li sintering kub nce, lub shrinkage, ceev, flexural zog thiab hardness ntawm ultra-fine cermets ua ntej nce thiab ces txo, nrog ib tug siab tshaj plaws tus nqi tshwm sim ntawm 1500 ° C;Qhov tsim nyog microwave sintering txheej txheem rau ultra-fine cermets Tom qab khaws cia ntawm 1500 ° C rau 30 feeb, lub zog flexural thiab hardness qhov tseem ceeb yog 1547MPa thiab 90.6HRA feem, uas tau nce 24.0% thiab 0.7% feem ntau piv nrog cov pa sintering.
